		A. 1.3 Interest Rate.  Section 1.3 of the Agreement is hereby
eliminated and replaced with the following:

		(a)	Unless Borrower elects an Optional Interest Rate as
described below, the interest rate is Bank's Prime Rate in effect from time to

		(c)	Optional Interest Rate.  Instead of the interest rate based
on Bank's Prime Rate, Borrower may elect to have all or portions of the
Revolving Line of Credit (during the Availability Period) bear interest at the
Offshore Rate plus two and one half percent (2.50%), as more fully described
in paragraph 1.3 (d) below (the "Optional Interest Rate"), during an interest
period agreed to by Bank and Borrower.  Each interest rate is a rate per
annum.  Interest will be paid on the last day of each interest period and, if
the interest period is longer than 30 days, then on the first day of each
month during the interest period.  At the end of any interest period, the
interest rate will revert to the rate based on the Prime Rate, unless Borrower
has designated another Optional Interest Rate for that Portion.

		(d)	Offshore Rate/Rate Plus Disclosed Spread.  Borrower may
elect to have all or portions of the principal balance of the Revolving Line
of Credit bear interest at the Offshore Rate plus two and one half percent
(2.5%).

		Designation of an Offshore Rate portion is subject to the
following 				requirements:

(i)	The interest period during which the Offshore Rate will be
in effect will be no shorter than 30 days and no longer than 180
days as selected by Borrower (except that Borrower may select an
interest period of 14 days so long as the Offshore Rate portion is
at least $1,000,000).  The last day of the interest period will be
determined by Bank using the practices of the offshore dollar
inter-bank market.

(ii)	Each Offshore Rate portion will be for an amount not less
than two hundred fifty thousand dollars ($250,000) (other than for
an interest period of 14 days, in which event the amount may not
be less than $1,000,000) and increments of fifty thousand dollars
above the minimum.

(iii)	The "Offshore Rate" means the interest rate determined by
the following formula, rounded upward to the nearest 1/100 of one
percent.  (All amounts in the calculation will be determined by
Bank as of the first day of the interest period.)

Offshore Rate = Eurodollar Rate
                                                   (1.00 - Reserve Percentage)

percentages for determining the reserves to be maintained by
member banks for the Federal Reserve System for Eurocurrency
Liabilities, as defined in the Federal Reserve Board Regulation D.

and other reserve percentages.

any portion of the principal balance of the Revolving Line of
Credit which is scheduled to be repaid before the last day of the

already bearing interest at the Offshore Rate may be converted to
a different rate during its interest period.

voluntary, by reason of acceleration or otherwise, will be
accompanied by the amount of accrued interest on the amount
prepaid, and a prepayment fee equal to the amount (if any) by
which:

(A)	the additional interest which would have been payable
on the amount prepaid had it not been paid until the last
day of the interest period, exceeds

(B)	the interest which would have been recoverable by Bank
by placing the amount prepaid on the deposit in the offshore
dollar market for a period starting on the date on which it
was prepaid and ending on the last day of the interest
period for such portion.

(C)	Bank will have no obligation to accept an election of
an Offshore Rate portion if any of the following described
events has occurred and is continuing:

(x)	Dollar deposits in the principal amount, and for
periods equal to the interest period, of an Offshore
Rate portion are not available in the offshore Dollar
interbank market; or

(y)	the Offshore Rate does not accurately reflect
the cost of an Offshore Rate portion.
